View Full Version : Repairing Chunk Out of the Hull - Fiberglass and Gel Coat
04-05-2012, 08:28 PM
I know there are tons of threads out there on gel coat and such, but I couldnt seem to find anything that helped much with my situation.
I have a 2010 x25 and took a divot out of the hull one day last summer (image attached). I brought it in and they quoted me upwards of $2,000, so I will be doing it myself.
I have bondo-ed and fiberglassed autos before, but never worked on the hull of a boat. Ive stopped by my local West Marine and they gave me some Gel Coat and other materials, but i was hoping that one of you may have done this before and could recommend steps, process, preferred materials, etc.
Thanks and really appreciate any and all help you can offer.

Where are you located on the west coast? There is a really good gel coat guy in Tracy.

For a 2010 I wouln't attempt a mix and match gelcoat repair. Buy some factory matched patch paste from Spectrum. It will be about the same price as a mix and match kit but you will just have to add hardener and you'll have a pretty much perfect match.
I've only done gel repairs with none deep enough to require filling with fiberglass first. I had to do mix and match on my '00 since 1) the factory matched stuff probably wouldn't have matched and 2) Spectrum didn't offer my color in anything less than a quart ($125ish IIRC).

Had a similar repair done in white, the hardest color to match, for about $100 by a professional. I could never tell where the repair was done (on a different boat than my own) and the cost was simply amazing. When it comes to white, don't waste your money on Spectrum. Just have a good gel coat specialist mix and match. White never works out of the box.

Here's what I did I have a thread on here for a repair I just did myself. Go on iboats.com find the appropriate gel coat patch paste kit it's $30.
Step one: use blue masking tape and tape around the damaged area lay the tape about a 1/16 from the start of the damage. Use 150 grit wet/dry sand paper and use your fingers to clean up the damaged area. You just wanna remove loose debris and scuff it.
Step two: clean it with acetone on a cloth don't use a circular motion that only spreads the wax and oils around clean wipe it with one stroke then flip towel and wipe clean again.
Step 3: mix one ounce of gel coat to 10-12 drops of hardner mix thoroughly with a Popsicle stick or plastic putty knife.
Step 4: start applying gel coat into damaged area with plastic putty work it in to get air out fill it flush with original area then use a heat gun on low about 10-12 inches away and move it on it till you can see it start shrinking don't heat it too much or it will start to cure and more coats won't bond as effectively. Repeat these steps and apply as many coats as you need to become about 1/16 to an 1/8 above the finished surface.
Step five: after it has cured overnight get a spray bottle fill it with water get a sanding block. Start with 150 grit wet and sand it till its close to flush with finished surface. Then go to 220 then 300 then 600 after you feel like its about there remove the tape wipe clean with a dry towel. Put new tape around the area again this time about an inch from the original damage line. Then use 1500 wet and blend the area in. Once satisfied remove all tape and use 3m marine buffing compound and apply by there directions listed on bottle.
Then boom its done like it never happened
